The IS-A105N is a high output, 105dB(A) alarm sounder.

Approvals include ATEX, IECEx and GOST-R for Zone 0 applications and FM approval for Class I Division 1 and Class I Zone 0 applications.

The IS-L101L unit is an intrinsically safe field mounting beacon which provides a bright flashing warning signal.

The unit can be used independently or combined with an IS-A105N 49 alarm sounder.

Combination units can utilise a common zener barrier or galvanic isolator and may be coupled together or mounted separately.

With the IS-A105N, the alarm-accept function can be utilised. By closing a pair of external contacts (i.e. push switch) the operator may silence the alarm for set periods between 5 seconds and 2 hours. If after the preset time the alarm condition still exists, the sounder will activate again.

IS-A105N features:

Input overload and reverse current protection

Auto synchronised sound output

Unit can be mounted using external lugs or internal BESA compatible fixing positions

Duplicate cable terminations (in and out for daisy-chain installations)
